Comparison of Endarterectomy and Stenting for High-risk Carotid Atherosclerotic Stenosis / 中国微创外科杂志

ABSTRACT

Objective To compare the efficacy of carotid endarterectomy(CEA)and carotid artery stenting(CAS)for the treatment of high-risk atherosclerotic carotid artery stenosis.Methods We retrospectively studied the surgical outcomes of 58 patients with high-risk atherosclerotic carotid artery stenosis.Among the cases,32 received CEA and 26 underwent CAS.All of the patients were followed up with carotid ultrasonography,CTA or DSA in 30 days,6 months,and 1 year after the procedures,their neurological function was assessed meanwhile.Cumulative incidence of death,stroke,or myocardial infarction within 30 days after the surgical intervention and death or ipsilateral stroke events between 30 days and 1 year were set as the primary endpoint of the study.And the secondary endpoints were the CEA or CAS-correlated complications or severe restenosis within 1 year after the treatment.The outcomes of the two groups were compared.Results The primary endpoint occurred in 3 patients in the CEA group(9.4%)and 4 in the CAS group(15.4%)(?2=0.086,P= 0.769).And the secondary endpoint was found in 4 of the CEA group(12.5%)and 4 of the CAS group(15.4%)respectively(?2=0.000,P=1.000).Conclusions For the patients with high-risk carotid artery stenosis and coexisting conditions,CEA is as safe and effective as CAS.
